Carbon disulfide burns with oxygen to form carbon dioxide and sulfur dioxide in the following manner: cs2 + 3o2 → co2 + 2so2

what is the volume of sulfur dioxide (so2 gas), formed when 2 moles of carbon disulfide (cs2) are burned? the reaction is taking place at stp.

5.6 l
22.4 l
89.6 l
44.8 l

89.6 L.

Explanation:

CS₂ + 3O₂ → CO₂ + 2SO₂.

Using cross multiplication:

1.0 mole of CS₂ produces → 2.0 moles of SO₂.

2.0 mole of CS₂ produces → ??? moles of SO₂.

∴ The no. of moles of SO₂ produced = (2.0 mol)(2.0 mol)/(1.0 mol) = 4.0 mol.

∴ 4.0 moles of SO₂ occupy = (4.0)(22.4 L) = 89.6 L.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
